Abstract (en)
[origin: WO2009136848A1] The present invention relates to electronic payments in a mobile communication system. In particular, the present invention relates to methods and arrangements for secure transmission using SMS in a mobile communication system. In a method according to the invention data and a PIN-code are stored in a memory in a mobile terminal. A first bit sequence is created from the data and the PIN- code where different 8-bit combinations represent each character of the data and the PIN-code. Next the first bit sequence is encrypted using a PKI (Public Key Infrastructure)public-key to create a second bit sequence. A sequence of characters is then created from the second bit sequence, where each character in the sequence of characters is represented by an 8-bit combination. The characters are then transposed to 7-bit characters to create a third bit sequence which is transmitted to a server using SMS. The data, the PIN-code and the first bit sequence are also erased from the memory in the mobile terminal.
